[cfe-dev] Matching bools

[Gábor Horváth]

Hi!

With "_Bool" it works flawlessly thanks. I wonder if isBoolean is an user
friendly solution, as one might except to use asString with any type.
However I admint, making asString matcher able to match everything might
add unnecessary complexity.

Thanks,
Gábor
